SafLager S-189 Lager Dry Yeast

Brew crisp, clean lagers with SafLager S-189 Dry Yeast, a Swiss lager strain known for its smooth fermentation profile and highly drinkable results. This versatile yeast produces neutral flavor expression, high flocculation, and strong attenuation, making it ideal for classic lagers, Kölsch-style hybrids, and other cold-fermented beers. It performs reliably between 53.6°F and 64.4°F for balanced, clean character.

SafLager S-189 is selected for its ability to produce exceptionally clean lagers with minimal ester formation. Its high attenuation range of 80–84% supports dry, crisp finishes while maintaining clarity and balance. This strain is commonly used in a wide range of European lager styles where neutral yeast character and smooth drinkability are essential.

Each 11.5 g packet ferments 5–8 gallons of wort and may be pitched directly, though rehydration at cooler temperatures can support optimal cell vitality for high-gravity or cold starts. When fermenting at the lower end of the temperature range, consider oxygenation and yeast nutrient to ensure complete and steady attenuation.

Widely used by home and professional lager brewers, SafLager S-189 offers predictable performance, clean flavor development, and dependable results across a variety of traditional lager styles.
